First up is the $69.99 Bluetooth keyboard that’s meant to work with any Android 3.0 and above Honeycomb tablets. Powered by 4 triple-A batteries, this keyboard features a low profile design, compact keys, dedicated media buttons, and a complementary case that actually doubles as a stand for a tablet.
With the second Bluetooth keyboard, which is priced higher at $99.99, it’s specifically made to work with the Samsung Galaxy Tab 10.1. That’s because it’s able to keep the tablet firmly at an angled position to make typing very easy for yourself – and much like the other keyboard, this one also doubles as a protective aluminum case for the tablet.
Therefore, if you simply don’t want to buy those first party accessories from the manufacturers directly, then you might want to consider snatching any of Logitech’s offerings.
